Late Thursday, Apple released a new beta for its forthcoming Mac OS X 10.6.5 update. The new build, labeled “10H562″ was released to developers late Thursday as a 616MB delta update. According to the release notes, there are no known issues. With new builds coming steadily for several months now, the update is expected to arrive in advance of the November release of iOS 4.2.

Per AppleInsider, the seed note accompanying the build specifies Printing as a “Focus Area.” 10.6.5 will work with iOS devices running iOS 4.2 to enable the new AirPrint wireless printing functionality. 10.6.4, the last update to Mac OS X 10.6, came in June with fixes to Adobe Creative Suite 3 issues and a resolution for unresponsive keyboards and trackpads.

Stay tuned for additional details as we get it and if you’ve gotten your mitts on the new build for testing, let us know.
